Man Utd prepare £20m bid for So'ton defender?

Premier league holders Manchester United are understood to be readying a summer transfer offer of around £20m for the services of one of the best full-backs in the Premier League.

According to Goal, the Red Devils manager David Moyes is keen on strengthening the club's defensive setup in the summer, as he plans to make a major reshuffle to the squad for the next season.

However, the Red Devils are likely to face stiff competition from Chelsea, who have been tracking the 18-year-old's performances in recent months.

In spite of the interest, Saints manager Mauricio Pochettino has insisted that Shaw is not for sale.
